cocos2d-x 2.2 android 使用已有静态库(*.a)，大幅减少编译时间

20140617 最新的2.2.3版本，请看这里 /article/10786607.html

*******分割线***********************

现在使用的版本是2.2 ，网上找了个参考贴 : /article/11197603.html

但是这个帖子里面用的版本是2.1 跟现在用的2.2有些目录结构不一样，而且跟本项目的使用环境也不一样（比如本项目里面用到了websocket）直接照搬会报错。

花了一下午研究，发现其核心就是:如果缺少xx库，就先在cocos2d-x-2.x的目录下找xx对应的文件所在的目录，然后就把该目录下的Android.mk里面的内容，挪到prebuild/Android.mk里面去(当然还得修改路径),同时把xx.a也挪到prebuild目录下.

下面整理一个本项目用到的最终cocos2d-x-2.2的完整解决方案：

1.假设{cocos2d-x-2.2}是你的根目录,{cocos2d-x-2.2}/projects/XXXCpp是你用python脚本生成的项目。

2.先在Elipse里面正常编译运行一次，{cocos2d-x-2.2}/projects/XXXCpp/proj.android/obj/local/armeabi/下面会生成若干*.a和一个.so和一个objs文件夹:



2.在{cocos2d-x-2.2}目录下，新建prebuild文件夹，拷贝{cocos2d-x-2.2}/projects/XXXCpp/proj.android/obj/local/armeabi/*.a 到这个文件夹

3.在{cocos2d-x-2.2}/prebuild下面新建一个Android.mk，内容如下:

说明：

1).红色所在行是我在原贴的基础上添加的，因为本项目用到了websocket，所以直接用原帖提供的Android.mk编译报错，先是说找不到libwebsockets.h,好不容易找到libwebsockets.h的目录在{cocos2d-x-2.2}/external/libwebsockets/，先把{cocos2d-x-2.2}/external/libwebsockets/android/lib/armeabi/libwebsockets.a拷贝到{cocos2d-x-2.2}/prebuild/下，然后把里面的{cocos2d-x-2.2}/external/libwebsockets/android/include/Android.mk文件的内容挪过来，并修改了路径，再加了相关的对应行。找不到libwebsockets.h的问题解决了，但是紧接着有报错说WebPxxx没定义(具体名称忘了)，继续跟Y死磕。又把libwebp的目录找到，模拟同目录的libjpeg等文件的添加方式加进来，编译终于通过了。

2).绿色的2行xml2相关的是被我在原文件的基础上注释掉了的。1是因为我们项目现在没用到xml2，2是因为现在libxml2的目录在2.2版本里面已经不在prebuilt目录下了，改到了{cocos2d-x-2.2}/cocos2dx/platform/third_party/emscripten/libxml2。等需要用到的时候再说。有朋友着急的话，可以参考前面的做法自行添加。

4.修改{cocos2d-x-2.2}/projects/XXXCpp/proj.android/jni/Android.mk，注释最后6行，再添加一行:

#$(call import-module,cocos2dx)
#$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)
#$(call import-module,CocosDenshion/android)
#$(call import-module,extensions)
#$(call import-module,external/Box2D)
#$(call import-module,external/chipmunk)
$(call import-module,prebuild)

5.Eclipse里面编译运行，大功告成！以后每次编译运行可以节省好几分钟（不用每次都重新生成*.a）如果不clean的话，直接增量编译，只需要等十几秒就出现选择安装设备的弹窗了。nice!
6.这个prebuild/Android.mk文件是一个动态变化的文件，随着项目的进展，如果使用了新的库或者发现明明在cocos2d-x框架里面的库但是出现编译报错，那么都可能需要返回第二步，重新走一遍流程！

7.感谢参考贴/article/11197603.html和参考贴的参考贴/article/4571621.html的作者们!
